1.关于喷锚支护锚杆支护是在地下洞室中用锚杆锚固在岩石内部,把围岩和基岩固结,加强围岩的整体性和坚固性而形成的支护体系。喷锚支护是锚杆、喷射混凝土和金属网单一或联合支护形式的统称。喷锚支护不是一种孤立的结构物,而是通过锚杆和喷射混凝土层对围岩产生综合的作用。其工作原理有:对要下坠的岩块有“悬吊梁”作用,使之锚固到深部坚固的岩石上;对层状围岩有“组合梁”作用,将层状岩体联结在一起,
1. About anchor-anchor support Bolt support is a support system formed by anchoring anchor bolts in the underground caverns, consolidating the surrounding rocks and bedrock, and strengthening the integrity and solidity of the surrounding rock. Shotcrete-anchor support is a general term for single or combined forms of anchors, shotcrete and metal mesh. Shotcrete-anchor support is not an isolated structure, but it has a comprehensive effect on the surrounding rock through bolts and shotcrete layers. The working principle is: “suspension beam” is applied to the rock blocks to be lowered, so that they are anchored to the deep solid rock; the “layered” surrounding rock has a “composite beam” effect and the layered rock bodies are linked together.
